The ketogenic diet, or keto diet, is a high-fat, low-carbohydrate diet that encourages the body to burn fat instead of carbohydrates for energy. This diet causes a metabolic state called ketosis, in which the body produces ketones, which become the main source of energy for the body and brain. Some people may find it challenging to stick to the keto diet, so they may take exogenous ketone supplements to help them achieve ketosis. However, it is important to note that exogenous ketone supplements are not regulated by the Food and Drug Administration (FDA), and there are potential side effects such as gastrointestinal symptoms and electrolyte imbalances. Therefore, it is recommended to consult a doctor before taking any exogenous ketone supplements.
| Characteristics | Values |
|---|---|
| Ketogenic diet | High in fat, moderate in protein, and low in carbohydrates |
| Keto diet composition | 70% to 80% fats, 10% to 20% proteins, and 5% to 10% carbohydrates |
| Ketosis | A metabolic state where the body burns fat for energy instead of glucose |
| Ketone supplements | Exogenous ketones that may induce ketosis without a strict diet; may cause side effects like gastrointestinal issues and electrolyte imbalances |
| Ketone supplement side effects | Stomach distress, electrolyte imbalance, hypoglycemia, dehydration, hypertension |
| Ketosis side effects | "Keto flu," bad breath, constipation, dehydration, low bone density, high cholesterol, kidney stones |

What You'll Learn
Ketogenic diets and ketone supplements
Ketogenic diets are highly restrictive and involve drastically reducing carbohydrate intake and replacing it with fat. This reduction in carbohydrates puts the body into a metabolic state called ketosis, where it becomes very efficient at burning fat for energy. Ketosis also has several health benefits, such as potential weight loss, increased energy, and treating chronic illnesses. However, it can be challenging to follow and may produce side effects like "keto" breath, constipation, dehydration, and low bone density.
Ketone supplements, or exogenous ketones, are synthetic or naturally derived ketones taken to help achieve ketosis. They can be beneficial for those who find it challenging to stick to a ketogenic diet. These supplements can elevate ketone levels in the blood, leading to ketosis. However, it is important to consult a doctor before taking them as they may carry side effects such as gastrointestinal symptoms and electrolyte imbalances.
To achieve ketosis through a ketogenic diet, one must limit their carb consumption to around 20 to 50 grams per day and increase their intake of fats, such as meat, fish, eggs, nuts, and healthy oils. It is also important to moderate protein consumption as high amounts can be converted into glucose, slowing the transition into ketosis. Intermittent fasting can help enter ketosis faster.
Ketone supplements are typically supplied as ketone salts or esters. Ketone salts are made by adding artificial ketones to electrolytes like magnesium, potassium, and sodium, which can increase electrolyte levels. Ketone esters have been shown to induce ketosis in participants of a study, but further research is needed to establish the accuracy of these findings.

Ketosis and its benefits
Ketosis is a metabolic state that occurs when the body burns fat for energy instead of glucose. Typically, carbohydrates in your diet provide most of the fuel your body needs. The keto diet, which encourages ketosis, reduces the number of carbs you eat and teaches your body to burn fat for fuel instead.
The keto diet is high in fat, moderate in protein, and low in carbohydrates. The standard keto diet consists of 70% to 80% fats, 10% to 20% proteins, and 5% to 10% carbohydrates. Many nutrient-rich foods contain high amounts of carbohydrates, including whole grains, fruits, and vegetables. Therefore, the keto diet restricts carbs from all sources.
Ketosis has been shown to increase focus and energy. Research suggests the brain works more efficiently on ketones than on glucose. The keto diet also delivers the body's energy needs in a way that reduces inflammation.
The keto diet is advertised as a weight-loss wonder, and it can indeed cause weight loss. However, it is a restrictive and challenging diet to follow. It can also produce side effects, including "keto" breath, constipation, dehydration, low bone density, high cholesterol, and kidney stones.
Exogenous ketones are supplements that can help induce ketosis without the need to follow a strict keto diet. However, the FDA does not regulate ketone supplements for their purity, safety, and effectiveness. Therefore, it is important to consult a doctor before taking any supplements.

Ketogenic diet restrictions
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. The keto diet encourages ketosis, in which the body burns fat instead of carbohydrates as its primary source of energy. Ketosis is a metabolic state that occurs when your body burns fat for energy instead of glucose.
The keto diet is highly restrictive, and people may find it challenging to stick to. It involves drastically reducing carbohydrate intake and replacing it with fat. Carbohydrates are typically restricted to 20 to 50 grams per day, and dieters fill up on fats, such as meat, fish, eggs, nuts, cheese, and healthy oils. It is important to moderate protein consumption as it can be converted into glucose if consumed in high amounts, which may slow the transition into ketosis.
The keto diet restricts many nutrient-rich foods that are high in carbohydrates, including whole grains, fruits, and vegetables. It also limits high-fibre foods, which have long-term health benefits. The diet can be difficult to follow and may produce side effects, including "keto" breath, constipation, dehydration, low bone density, and high cholesterol.
Some people may choose to take exogenous ketone supplements to help them achieve ketosis if they find it challenging to stick to the ketogenic diet. However, it is important to consult a doctor before taking any supplements, as they may carry risks of side effects such as gastrointestinal symptoms and electrolyte imbalances.

Ketone supplement side effects
Ketone supplements are generally considered safe and effective for increasing ketone body concentrations. However, there are some side effects associated with their consumption.
Firstly, ketone supplements can cause gastrointestinal symptoms such as nausea, diarrhoea, and stomach discomfort or distress. This is more commonly reported with ketone salts than ketone esters. Stomach upset can limit the number of supplements a person can take.
Secondly, there is a risk of electrolyte imbalances when taking ketone supplements, especially ketone salts, which can increase electrolyte levels. Electrolytes are vital for the proper functioning of muscles and the normal rhythm of the heart. Therefore, electrolyte imbalances can be particularly harmful to those with kidney disease.
Thirdly, hypoglycaemia, or low blood sugar, can occur as a result of ketogenic diets and ketone supplements. This can make individuals feel weak and lethargic.
Additionally, the keto diet, in general, may lead to side effects such as "keto flu", which includes symptoms like an upset stomach, headache, and fatigue. Other potential side effects of the keto diet include bad breath, constipation, dehydration, low bone density, high cholesterol, and kidney stones.
It is important to note that the Food and Drug Administration (FDA) does not regulate the exogenous ketone supplement market. Therefore, individuals should consult a doctor before taking ketone supplements to evaluate their overall health, electrolyte levels, and existing conditions to ensure the supplements are safe for them.
